To all whom it may concern:

Be it known that I, PAUL Prox, a sub'ect of the Emperor of Germany, residing at hicago, in the county of Cook, State of Illinois, have invented a new and useful Protector of Fabrics Against Moths and the like, and a Method of Making the Same, of which the following is a specification.

This invention relates to a protector of fabrics, furs and the like, against attacks by moths and other insects and which comprises a combination of a chemical substance suitable for preventing the attack of insects on clothing, with a carrier for said chemical substance; the invention also relates to the process of manufacturing this article and comprises the steps for permanently applying said chemical substance or chemical substances to said carrier.

Valuable clothing, fabrics, furs and the like are frequently protected against moths and other insects by sifting flakes of camphor into the folds and pockets of the fabrics, or by placing camphor balls into the objects to be protected. The flake material readily evaporates, but always leaves traces in the folds or seams of the fabrics and furs,

which is detrimental to the appearance of the same. Oamphor balls in tune become brittle, leaving granular material which is difficult to remove in folds or seams of the garment to the great discomfort of the wearer.

An object of thepresent invention is to combine permanently with a flat carrier in the form of a card board or the like a chemical substance of higher elficiency as a protective means against moths and similar insects, than camphor in flake or ball form, this chemical substance adhering to the carrier in the form of a coating and retaining its strength even after-long, continued use.

Another object of the invention is to devise a novel method of permanently applying this protective substance to a carrier b v dipping the carrier into a liquid substance and lettin the substance harden on the outer surface 0 the carrier. Permanency of connection between carrier and chemical substance is assured by rendering the surface portion of the carrier porous to a high degree or by softening said portion prior to the dipping into the chemical liquid, so that ;his substance only adheres to the outer sura ce The drawing illustrates perspectively one of the protectors made in accordance with the claimed method.

The Erotec tor comprises a flat carrier 1 prefera ly made of wood-pulp or other cellulose material and may consist of ordinary card board. The upper half of the carrier is left free of the chemical substance 2 which adheres to all surface portions of the carrier in its lower half. While the u per half may be used as display portion or an imprint, as, for instance, when the rotector is used as an advertising medium or clothing manufaciurers and dealers. the lower half is coated with the chemical substance.

This chemical substance preferably consists of the crystallized or hardened product of a mixture containing h drocarbons or nitro-deriv itives of hydrocar ons of any kind. One 0:? the preferred mixtures is nitronaphthalene or dinitronaphthalene with phenol, 9 parts by weight of dinitronaphthalene being mixed with 2 parts of phenol and being suiliciently heated to be convertcoated with tl 1e chemical substance. After the carrier has received a coating it is left to dry. After the coatin has become dry, another coating is applie and this process may be repeated whereby several layers are formed, as indicated at 3, 4 and 5 in the drawing.

The protect or manufactured in this way merely comprises a coated cardboard, and can easily be put into pockets or between folds of garments, without becom' brittle or crumbling away. It is more e cient in its protection against moths than camphor,

can readilybe removed and reused, can be manufactured at low cost, can not be lost by phenol is waste (as flakes) and may readily be eomof the cardboard only and mechanically combined with advertisements. bined therewith.
